Callata vs Ooma Office: 5-User Bundle or Per-User Plans?

Short answer: Ooma Office charges per user ($19.95 to $29.95 per user per month on its published plans), while Callata charges $99 per month including 5 users, then $20 per additional user. Against Ooma Office Pro, Callata costs about the same at four users and less from five; for one to three people, or for offices that want physical desk phones and a toll-free number in the box, Ooma is the stronger choice.

This comparison uses Ooma's published plans page as checked on October 1, 2026, and Callata's own product and pricing pages. Prices exclude taxes and regulatory fees.

How each one charges

Ooma Office sells three self-serve plans plus a custom Enterprise tier. Every self-serve plan is priced per user, per month, with no contract required, and Ooma lists a one-time $29.95 activation fee in its checkout subtotals.

Callata sells a single plan, Callata Office, at $99 per month. That price covers 5 users (each additional user is $20 per month), up to three local business numbers, unlimited inbound calling and a pooled allowance of 1,500 outbound US and Canada minutes per user per month, then $0.01 per minute. Business texting requires carrier 10DLC registration, which costs a one-time $49. Optional AI agents are billed separately from prepaid AI minutes at $0.25 per minute.

What a team actually pays

Because Ooma's price scales with every user and Callata's only rises after the fifth, the right answer depends on how many people need a line. Here is the monthly list price on Ooma Office Pro, the lowest Ooma plan that includes texting, against Callata.

Team size	Ooma Office Pro	Callata Office	Difference per month
1 user	$24.95	$99	Ooma is $74.05 cheaper
2 users	$49.90	$99	Ooma is $49.10 cheaper
3 users	$74.85	$99	Ooma is $24.15 cheaper
4 users	$99.80	$99	Callata is $0.80 cheaper
5 users	$124.75	$99	Callata is $25.75 cheaper
10 users	$249.50	$199	Callata is $50.50 cheaper

At five users, the gap is about $309 per year, before Ooma's activation fee. If you only need voice and can live without texting, Ooma Essentials at $19.95 per user is cheaper than Callata up to four users ($79.80) and within about a dollar of it from five to twenty users ($99.75 versus $99 at five, $399 each at twenty).

Feature differences that matter

Texting

Ooma Essentials has no text messaging. Pro caps texting at 250 messages per month and Pro Plus at 1,000, with bulk SMS packages quoted by phone. Callata's team texting uses a shared inbox for your business number with templates, delivery receipts and AI reply suggestions. Callata does not publish a monthly message cap, but every US business texting from a local number must complete 10DLC registration first, and Callata's messaging policy and fair-use terms still apply.

AI on calls and voicemail

On Ooma, AI Transcriptions and AI Insights are part of Pro Plus, and the AI Receptionist, AI Answering Service and AI Productivity Agent Bundle are add-ons on every plan. On Callata, every recorded call is transcribed and summarized with sentiment and action items, and every voicemail is transcribed and triaged for urgency, with a callback scheduled around your business hours. Callata's AI agents (receptionist, sales, support or scheduler) are optional and draw from prepaid minutes at $0.25 per minute.

Hardware and apps

This is where Ooma is clearly stronger. Ooma sells desk phones and base stations, and its plans include a mobile app (all plans) and a desktop app (Pro and up). Callata runs in Chrome, Edge, Safari or Firefox and can ring your cell phone at the same time; it does not sell desk phones or offer a dedicated native app. If your front desk wants a physical handset, Ooma fits that workflow better.

Video and team chat

Ooma Pro includes video meetings for up to 25 participants, and Pro Plus raises that to 100 and adds team chat. Callata is a phone and texting system only. If you were planning to use Ooma as your meeting tool too, factor in the cost of a separate video product.

Toll-free and fax

Ooma includes one toll-free number on each plan (with 500 inbound minutes per month) and lists digital fax among its plan features. Callata offers local numbers only and does not offer fax.

Support

Ooma's plans page says every plan comes with real-time customer support, and it publishes a sales phone line. Callata's support runs through email at [email protected], with a stated reply time of one business day. If you expect to call a vendor in the middle of a busy afternoon, Ooma's support model is a better match. If most of your questions can wait a few hours, email support is usually enough for a small team.

Where Ooma is the better pick

• You have one to three users and want the lowest monthly bill.
• You want desk phones from the same vendor that runs the service.
• You need a toll-free number, fax or built-in video meetings.
• You want a vendor with a long operating history; Ooma has sold business phone service for years, while Callata is a newer product.

Where Callata is the better pick

• You have five or more people who need to make and take calls.
• You want texting, call recording and voicemail transcription without paying for a higher tier per person.
• You want AI call summaries on every recorded call rather than only on the top plan.
• Your team already works from laptops and cell phones, so a browser softphone plus cell ringing is enough.
• You want optional AI agents that answer after hours and bill only for minutes used.

Switching checklist

• Count how many people actually need to place or answer calls.
• Note whether anyone depends on a desk phone, fax line or toll-free number.
• Gather a recent Ooma bill, account holder name and service address for the port.
• Start Callata's 10DLC texting registration early; approval usually takes 3 to 10 business days.
• Keep Ooma active until the port completes, then cancel.
